Got some decent Gfx power there for games and enough cores to see PS happy. Can also double the RAM if you wanted to do so.
The 720 is very Capable

siumatfung: I Was going with the Specs saying due to AMD CPU Limitations, you can only use 1 stick of mem per channel... and the Tri-Channel AMD Core made me think otherwise....
Best do some more homework...

Number of memory channels is not the same as number of cores!
Core(s) on processor talk to memory via memory controller. Until recently this used to be in the "north bridge" chip in the chipset. AMD integrated the north bridge into the CPU a bit ago and with i7 Intel have followed this as well.
Ages ago CPU used to talk directly to memory but as cpus got much faster and memory didn't cpus started to have caches, then L2 caches and L3 caches to try to avoid the long waits for data from memory. During this process another method of increasing speed from memory was to have two-channel memory - think of it as if you had 2 seperate memories with one for odd addresses and one for even addresses - that way the chip could get twice as much data in one access as with a single channel ... Intel have clearly decided even this isn't enough and gone for 3 channels. Note, there is a cost for this as each channel needs a lot of pins (thats whi i7 has ~1300 pins) + uses more power.
Current situation is that i7 is tri-channel but everything else is dual channel.

yeh was about to say what the guy above said but didnt know what to say anyways depending on how much data you want to store on the PC 1Tb might be overkill swap it for a 500Gb or the samsung 640Gb
Ok, so after a bit of looking into things...
I'd like
- AMD Phenom II 3.0Ghz CPU (To be OC'd in the Future)
- 8Gb RAM
- 24" Monitor (Was going 26", but 24 should be big enough) Must Have HDMI, so i can plug PS3 in
- I'll now need a nice case (Piano Black Finish if poss, or Black alu)
